Prehistoric: Guang Chengzi Traveled Through Time After Being Struck by Lightning

Kunlun Yuxu Peak practiced swordsmanship and struck out the wrath of heaven, and a tribulation thunder blasted Guangchengzi into a rift in time and space. When he opened his eyes again, it was already a strange world. No one recognized the name of the head of the Twelve Golden Immortals, and only half of the sword was left in his hand. But I'm not afraid. I just threw away all the rules of Chanjiao after a new job - first find a hilltop and dominate it to become the king.
